How do oxidation numbers determine if an element is a metal or a nonmetal?
Generally, metals attain positive oxidation numbers only. Non metals can have either positive or negative oxidation states. If an oxidation number is a negative value, it can be deduced that it's a non metal element.
Is it true that non metal oxides which react with water to form acids are called acidic oxides?
non metal oxides react with water to give oxyacid but also do undergo disproponation depending on the oxidation number ( oxidation number is increased and decreased, respectively) of the metal N2O5 + H2O → 2HNO3 3NO2 + H2O → 2HNO3 + NO
What is the oxidation number for Br in BrO3-?
If Br had an oxidation number of +7, the net charge on the ion would be +1, and not -1. Thus, the oxidation number for Br in BrO3- should be 5+.
What is the oxidation number for copper metal?
zero
What is the oxidation number of Ag metal?
Zero The oxidation number of an element in its elemental form is always zero.
What is the oxidation number of hydrogeon when it is combined with a metal?
Hydrogen is a non metal. Metals are electropositive than hydrogen. Therefore, hydrogen atoms in metal hydrides have oxidation number -1.

What oxidation number would you find on a metal ion and a non - metal ion?
A metal and a nonmetal would form an ionic bond. In an ionic compound, a metal ion would have a positive oxidation number equal to its ionic charge. A nonmetal would have a negative oxidation number equal to its ionic charge.Examples:NaCl oxidation numbers: sodium has an oxidation number of +1, chloride has an oxidation number of -1. So the overall charge of NaCl is zero.CaCl2 oxidation numbers: calcium has an oxidation number of +2, the chloride ion has an oxidation of -1. Since there are two chloride ions, the total negative oxidation number is -2, so CaCl2 has an overall charge of zero.

Is cooper a metal or a non metal?
Yes, it is. It shows two oxidation states: Cu(I) and Cu(II).
What is the oxidation number for copper metal?
zero
What is the oxidation number of Ag metal?
Zero The oxidation number of an element in its elemental form is always zero.
What is the oxidation number of lithium metal?
Oxidation number of Li is +1. Oxidation number of oxygen is -2.
What is the oxidation number of hydrogen in the compound NH3?
The assumed oxidation number of nitrogen in ammonia (3+) in this question, is wrongly signed:The correct oxidation number if nitrogen in NITRIDES (like in ammonia NH3, ammonium NH4+ and amino groups -NH2) is minus 3, so hydrogen has oxidation value of plus 1(one, like in H+) which is in fact the only possible form when attached to nonmetals.
Which element has largest oxidation number?
Manganese is a metal element. It shows the largest oxidation number.
What is the Oxidation number of H?
Hydrogen has an oxidation number of +1 in most of its compounds and -1 in metal hydrides and hydrocarbons.
